How to rewrite the URL using asp.net core

Question

I'm a desktop developer. But i need to learn how to do web development using ASP.net Core. So i am here now asking question. How do i properly rewrite the URL of my website:

This is the structure of my website

This is how I Add link to my layout page

<li><a asp-action="Index" asp-controller="Home">Home</a></li>
<li><a asp-action="Excel" asp-controller="Excel">Excel</a></li>

What is want to do is rewrite this URL

http://localhost:64419/Excel/Excel

Currently I am using this middleware

https://www.nuget.org/packages/Microsoft.AspNetCore.Rewrite/

And this is my code

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseDeveloperExceptionPage();
            app.UseStatusCodePages();
            app.UseStaticFiles();
            app.UseMvc(routes =>
            {
                var rewrite = new RewriteOptions()

                .AddRewrite(@"ExcelOnly", "Excel/Excel", skipRemainingRules: false);

                app.UseRewriter(rewrite);

                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}"
                    );

                routes.MapRoute(
                   name: "excel",
                   template: "{controller=Excel}/{action=Excel}"
                   );
            });
        }

Because of the code above I was able to rewrite the URL into

http://localhost:64419/ExcelOnly

By simply typing the Link in the URL.

But when I clicked on the Link in the Layout page. The page is loaded but it uses the link http://localhost:64419/Excel/Excel how can I properly rewrite the URL.

What are the things I need to search. I can't find a solution. Maybe I'm using the wrong search term. So I decided to ask here.

Thank you.

Update:

I was able to redirect the page in the URL i want

with this code

var rewrite = new RewriteOptions()
                .AddRedirect("Excel/Excel", "ExcelOnly")
                .AddRewrite(@"ExcelOnly", "Excel/Excel", skipRemainingRules: false);

                app.UseRewriter(rewrite);

But is it a good practice? I always need the Controller and the Action in each of my redirect. So if i changed the Action name i also need to change the redirect and rewrite.

And another problem. When I hover the mouse in the link it shows the path http://localhost:64419/Excel/Excel so how can I hide this stuff?

Thank you

URL rewriting can reduce the performance of an app. Where feasible, you should limit the number and complexity of rules.

If you want to route to Excel Action in Excel Controller with URL ExcelOnly, you could try Route like below:

    public class ExcelController : Controller
{
    [Route("ExcelOnly")]
    public IActionResult Excel()
    {
        return View();
    }
}

It will generate <li><a asp-action="Excel" asp-controller="Excel">Excel</a></li> to

<a href="/ExcelOnly">Excel</a>

And when you enter http://localhost:64419/ExcelOnly, it will route to Excel action in Excel controller.
